PowerPoint 3:
BedZED (Beddington
Zero Energy
Development)
BedZED claims to be the UK’s largest sustainable community. Built in
2002, it has 100 homes designed to provide ordinary people with a high
quality of life while living within their share of the earth’s resources.
BedZED, in Beddington, south-west London, was built on a brownfield
site on previously industrial land. Fifty per cent of houses are for private
sale or rent, 25% for shared ownership and 25% social housing for rent

In a BedZED home energy use for heating and hot water is reduced 81%
by simple things like south-facing windows and triple glazing. Electricity
consumption is reduced 45% by low-energy lighting and appliances
BedZED walls are thicker than average, with insulation between the
bricks to prevent energy loss. The building materials have used less
energy to make and, where possible, are locally produced
A combined heat and power plant was designed to burn BedZED waste
to produce hot water and electricity. But technical and commercial
difficulties mean the system is not in operation and will be replaced.
Effluent from the buildings is treated on site and the water is used for
flushing toilets
A distinctive feature of the buildings is the wind cowls on the roofs.
These cowls ventilate the houses and recover heat from the air
coming out. The roofs are covered by solar panels (to generate
electricity) and plants (for insulation and a habitat for wildlife)
People separate their waste in their kitchens to make recycling and
composting easier. Sixty per cent of waste is recycled, three times the
UK average. Residents encourage each other to recycle
BedZED has a green transport plan to reduce car mileage. There is a
car-sharing club and electric car charging points. Good public transport
links and cycle storage spaces are also provided

Your Task:
• For the exam you will need to know
case studies of urban issues in
MEDC’s and LEDC’s
• So far for MEDC’s we have done
Bath and Salisbury
• Now you are going to research
Bedzed ….
Bedzed: your work
The exam board syllabus says you
need to know a
“case study of sustainable housing”
An exam question from 2010 said
“Use one or more named case
studies to describe the features of a
sustainable settlement.” (8 marks)
What you need to do….
• Introduction: What is Bedzed and where
is it?
• Main part: What have they tried to
achieve/ how have they tried to achieve
it? Split into sections such as: energy,
transport, community, housing etc)
• Conclusion: what do you think of their
achievements? Is Bedzed a success?
Refer to the evidence you have
collected
What you need to do…. (part 2)
• Next lesson you and your group will produce a
presentation about Bedzed. You need to cover
all the points from the previous slide. You
should refer to Egan Wheel ideas and do some
internet research as well
• You can present this in ANY WAY YOU WISH
(poster, powerpoint, drama, TV show, estate
agents ad, ANYTHING)
• You need to split the class into groups of 3 or 4
• The rest is up to you
